Abstract
The invention is directed to an apparatus and method for both supporting and preserving a piece of graft tissue during pre-implantation preparation, and for creating a tubular graft from the piece of graft tissue. The purpose of the device is (1) to support, stabilize, and preserve a piece of graft tissue; (2) to provide a rotating base to debride or otherwise prepare the donor tissue; and (3) to place the tissue around a mandrel for tubularization. The apparatus may be used as a support for preparing a piece of tissue for use as a skin graft or the like. Additionally, the preferred embodiment of the invention provides an advantageous method and apparatus for forming the graft tissue into a tubular configuration for use as a tubular graft.
